I've had 2 sets of 9-speed Micronew (budget line of Microshift?
) brifters, they worked very well with shimano mech and brakes. One set was on a commuter bike and they've done several thousand miles in all-weather conditions and survived a few acciddents. Never skipped a beat. I prefer them to Shimmies
I've bought Sensah in the past and returned them, as I thought they were a step down from the humble microshifts.
I've then switched to 9-speed shimergo (Campy 10x speed shifters with shimmy 9 speed mech & SRAM cassette) and that's my preferred set-up. I've installed a Micronew rear mech in the shimergo set-up on one of my bikes, and it works just as well as Dura-ace shimmy, as long as you do the wraparound cable trick (which, admittedly, is a bit easier to do on some shimmies).
On a related note, the Chinese "noname" (mine are "Deckas", but usually there's a new name invented every 6 months) narrow-wide front alloy chainrings are fantastic by the way, but I don't think that Microshift ever put their name on them.
I thought that Micronew 7 & 9 speed flat bar shifters were uninspiring.
